For fans of Ahsoka and Star Wars: Rebels, seeing Bokken Jedi Ezra Bridger again warmed hearts. However, the reappearance of another Rebels mainstay, Grand Admiral Thrawn, chilled them from hearts to spines.

He is still poised, calm and deadly, even though everything from his ship to his uniform has seen better days.
